摘　　要：[目的]探讨露珠杜鹃容器苗分级标准。[方法]采用逐步聚类分析方法,以苗高和地径为苗木分级的质量指标,用欧氏距离法对初始分级结果进行修正。[结果]Ⅰ级苗苗高≥8.5 cm,地径≥0.24 cm;Ⅱ级苗苗高≥5.3 cm,地径≥0.21 cm;Ⅲ级苗苗高<5.3 cm,地径<0.21 cm。[结论]该容器苗苗木分级标准可为露珠杜鹃的大面积培育和开发利用提供参考依据。[Objective]The aim was to analyze the grading standards of Rhododendron irroratum Franch.container seedlings.[Method]By using the methods of gradual clustering analysis,seedling height and basal diameter were proposed as the quality indexes of seedling classification.Then,correcting the initial grading results on the basis of euclidean distance method.[Result]The height≥ 8.5 cm and basal diameter≥ 0.24 cm were viewed as grade Ⅰ seedlings;the height≥5.3 cm and basal diameter≥0.21 cm were viewed as grade Ⅱ se...
